CAR-TRUCK.

Specification of Letters Patent.

Patented Oct. 23, 1906.

Original application filed December 23, 1903, gerial No. 186,399.Divided and this application filed September 10, 1904. Serial No.223,992.

citizen ofthe United States, residing at Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Car-Trucks and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to improvements in car-trucks, and particularlyto certain features of improvement of the equalizer-bars andconnections.

The object of the present invention is the production of a short baseequalizer bar truck which shall have the equalizer-bar springs locatedfar enough apart to prevent undue oscillation of the truck-frame.

With this and further objects in view the invention consists in certainnovel construc tions, combinations, and arrangements of parts, as willbe hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents a view in sideelevation of a cartruck comprising the features of the presentinvention, the parts being broken away. Fig. 2 represents a top planview of the same. Fig. 3 represents a transverse vertical section takenon line 2 2 of Fig. 2. I

In'the present art it is desirable to support a car-body in such manneras to prevent undue vibration of the same during transit,

and in securing the best results I employ a structure involving thefeatures delineated in the accompanying drawings, in which.

1 1 represent side frames of a car-truck, each formed ofla single pieceof-material bent into yoke shape, producing a pedestal 2 at each end.End frames 3 connect the ends of the side frames .1. Said side framesare also connected intermediate their length by transversely-arrangedtransoms 4 4, between which transoms is supported a bolster 5 of anypreferred type, said bolster resting upon elliptic or other suitablesprings 6, carried by depending yoke-bars 7, connected to the transoms4. Each of the opposite ends of each side frame 1 partially incloses ajournal- 1 box 8, carried by one end of an axle 9, said axles 9 beingprovided with the usual supporting-wheels 1010. Each box 8 carries'great distance.

on its outer side a pair of vertical flanges 16, between which flangesare arranged wearingplates 17 17, engaging the respective pedestal 2 ofthe given side frame 1. The side of each box 8 opposite that carryingthe flanges 16 is provided with a laterally-proiecting lug 18,

forming the seat of a cushion1ng-spr1ng 19.,

supporting the respective end of the glven side frame 1. Anequalizer-bar 19 connects each pair of boxes 8 at one side of thecartruck, each equalizer bar 19 consisting of parallel plates spacedapart with their ends resting upon the upper surface of the connectedboxes 8, said plates beingbent down- 'wardly just inside the boxes 8 toa plane below such boxes and extending horizontally for a greaterportion of the distance between the boxes. The downwardly-extendingportions of said plates inclose the lug 18 and are secured thereto bysuitable bolts 20, said plates being positioned outside the verticalplane of the'given frame 1, permitting vertical movement of the samebetween the ends of the plates.

The'equalizer-bars 19 carry suitable brackets 21, supporting abrake-rigging, preferably of the type fully illustrated and described inmy application for Letters Patent for improvements in brakes, filedDecember 23, 1903, and designated by Serial No. 186,399, of which thisapplication is a division.

In order to produce a short wheel-base equalizer-bar truck free fromundue oscillation of the truck-frame, the equalizer-bar springs 19 arespaced apart a relatively The placing of the equalizer bar springs 19close to .the journal-box 8 between the plates of the equalizer-bar's 19gives the required space between the springs I mitted by the bars 19 tothe top of thejour nal-boxes 8. Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent,is

1. In a mechanism of the class described, the combination with a pair ofaxles and journal-b oxes therefor, of a divided equalizerbar extendingbetween each pair of journalboxes, a lug extending from each journal-boxbetween the parts of the respective equalizeribar, and side framessupported upon said ugs.

2. In a mechanism of the class described, the combination with a pair ofaxles and journal-boxes therefor, of two-piece equalizer-bars connectingthe pair of boxes, a lug projecting from each of said boxes between theparts of the respective bars, means securing said lugs to said bars,side frames, and a cushion resting upon said lugs supporting said sideframes. 3. In a-mechanism of the class described, the combination with aair of axles and journal-boxes therefor, o' a one-piece side frame bentinto yoke shape producing a pedestal at each end inclosing each pair ofboxes, flanges extending from the respective boxes upon the sides of'therespective pedestals, divided equalizer-bars connecting said airs ofboxes, means connecting said equa izer bars to said boxes, and meanssupported by said connecting means.

4. In a mechanism of the class described, the combination with a pair ofjournalboxes therefor, of a lug extending inwardly from the innervertical face of each of said journal-boxes, divided equalizer-barsconnecting said boxes and inclosing said lugs, and means extendingthrough said bars and lugs for rigidly securing the bars with the 5. Ina mechanism of the class described, the combination with a pair of axlesand journal-boxes therefor, of equalizer-bars connecting said.journal-boxes, a lug extending from each of said journal-boxes, meansconnecting said equalizer-bars to said lugs, and side frames supportedby said lugs.

6. In a mechanism of the class described, the combination with a pair ofaxles and journal-boxes therefor, of equalizer-bars connecting saidboxes, lugs projecting laterally from the vertical faces of said boxes,and means rigidly connecting said equalizer-bars with said lugs.

7. In a mechanism of the class described, the combination with a air ofaxles and journal-boxes therefor, of an equalizer-bar connecting eachpair of boxes, each bar hav ing its ends resting upon the top of therespective boxes and being bent downwardly past the inner vertical faceof the respective box, a lug projecting horizontally from said faceofthe respective box, means rigidly connecting the respectiveequalizer-bar with the respective lug, and car-framesupporting meanscarried by said lug.

8. In a mechanism of the class described, the combination with a pair ofaxles and j ournal-boxes therefor, of a divided equalizerbar connectingeach pair of ournal-boxes, a lug projecting laterally from the innervertical face of each of said boxes between the parts of the respectiveequalizer-bar, and side-frame sup orts mounted on said lugs.

9. In a mec ianism of the class described, the combination with a pairof axles and journal-boxes therefor, of a divided equalizerbar rigidlyconnecting each pair of journalboxes, springs located between the partsof the equalizer-bar, and side frames supported. by said springs.

10. In a mechanism of the class described, the combination with the pairof axles and journal-boxes therefor, of a divided equalizer-barextending between and rigidly secured to each pair of journal-boxes,springs located between the parts of the equalizerbar and side framessupported by said springs.

11. In a mechanism of the class described, the combination with a pairof axles and journal-boxes therefor, of a divided equalizer-bar rigidlyconnecting each pair of journal-boxes, springs supported between theparts of the equalizer-bar, and side frames supported by said springs.

12. In a mechanism of the class described the combination of a pair ofaxles and journal-boxes therefor of equalizer-bars having their endsresting upon said journal-boxes, the intermediate portion of said barsbeing depressed, a lug extending from each of said journal-boxes, andmeans rigidly connecting a part of the depressed portion of saidequalizer-bars to said lu s.

13. In a mechanism of the class described, the combination of a pair ofaxles and journal-boxes therefor, of equalizer-bars having their endsresting upon said boxes and being depressed intermediate their lengthpast the said journalboxes, lugs projecting from said journal-boxes andcrossing that part of the depressed part of said equalizer-barscxtending past the journal-boxes and means rigidly connecting said lugsto said equalizer-bars.

In testimony whereof I affix my signature in presence of two witnesses.
